Low Power Design Cells in VLSI

🔸 Why Do We Need Special Low Power Cells? In modern SoCs: Multiple voltage domains exist Blocks can be powered OFF independently Signals cross between domains 👉 This creates challenges like: Voltage mismatch Floating signals Data loss As low power methodologies evolved, special cells like level shifters, isolation cells, and retention flops became essential for correct functionality. 🔹…

Temperature Monitoring - Part 1

One of the components I ordered last week was the TC74 digital temperature sensor. I got the 5v version so I also got an adafruit level shifter.

My first task was to solder the pins onto the level shifter, my first attempt at soldering in almost 20 years since CDT lessons at school. It looks a little messy but not bad for my first attempt.

I've now connected it all up, following Jan Wagemakers guide inserting the level shifter to the clock and data lines. Using the i2c tools I can now get the temperature by issuing a command.

Next Steps - move the setup onto some stripeboard and solder it all into place. Also I need to work on the software side to log the data periodically rather than just on demand via a command.
